Yet I have the feeling GCP is the one which has been improving the most the quality of its offering.
It's interesting to monitor what's happening with data-warehouses for instance.
It almost feels AWS is having its "Kodak moment" with Redshift: a very remunerative but old technology in which they are deeply invested in.
It prevents them to put more effort behind solutions that decouple compute from storage (see Athena) and as a result they are offering a subpar competitor to BigQuery.
